In fact, it's mainly a heart disease that she can't even express to you!

Only show your love, the first important thing is to let her rest assured, to let her know clearly that no matter how old she is you will always take care of her.

The second is to let her know that when she is not feeling well, she will not drag her family members will not make them annoyed, and the family's financial condition will not be abandoned; people will inevitably be sick, but the family will be the same to do everything possible to take care of her. (A few decades ahead of her time, because of the economic conditions, the elderly sick is indeed a negative burden, also became a long time sick without filial son)

Third also let her know that she is sick, you will do all the scientific means to assist the doctor treatment. But make sure you listen to the doctor and not the prescription!

Good luck to you!
